RE: db-links question
Alex, Yes, the connection remains open unless it is explicitly closed (see Note: 1034343.6). The session also takes out a lock on the local RBS (see Note:74811.1) as this could be part of a distributed transaction. If this is a long running query this can lead to abnormal growth in the RBS since the active transaction in the RBS will prevent the RBS from wrapping into that extent. You can avoid this by issuing SET TRANSACTION READ ONLY; prior to running the distributed query. AFAIK, you can use MTS connections, although I would recommend using dedicated connections for any links used for replication (push and refresh operations).

Re: db links...
Hi,
Create {public} database link LINK
connect to remote_db_username identified by remote_db_username_password
using
'connect_string_as_found_in_tnsnames_on_machine_where_you_create_database_link';
There may be some issues with global name settings that may force you to
name the database link exactly the same as the global name of the remote
database.

Re: db links...
Hi saurabh, There are two types of database links. Explict database link the syntax is :- CREATE DATABASE LINK db link name CONNECT USING user_name identified by passwd USING connect_string; Default database link the syntax is :- CREATE DATABASE LINK db link name CONNECT USING current_user USING connect_string; In this case, it will try to connect to the remote database with the user_name / passwd of the local database currently logged in. to access table /view/synonym from a remote db use select * from table_name/view_name@dblink_name; But to make this db link and then to access first make the connect string of the remote database in the local machine in the tnsnames.ora using net 8 easy configuration tool. --- Saurabh Sharma [EMAIL PROTECTED] wrote: hi all, can any body has idea of how to create db links. we have 4-5 servers some are test and some producn. while requiring some info from other DBs how do i refer them ythrough DBlinks.

Re: db links...
Creating db link is pretty easy. This can be done easily by reading the documentation. On the other hand, think carefully to what you want to do. What do you want to access and who will access it.
